• Object-oriented programming (OOP) are NOT features added to existing program-
ming language such as structural programming language for example, Pascal or C.
• It is a new way of looking at the world around us with a view to solve problems.
• OOP depends on agents and community of agents and to communications and mes-
sage passing between cooperating agents of a community to solve a problem and pro-
vide services.
• Agent is called as object and the community of object is termed as ‘class on OOP paradigm’.
• Object is encapsulation of behaviour (method) and member data (attributes).
• A class encapsulates objects and objects behaviour is dictated by object methods.

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
